Risk early-warning of natural disasters is a very intricate non-deterministic prediction, and it was difficult to resolve the conflicts and incompatibility of the risk structure. Risk early-warning factors of natural disasters were differentiated into essential attributes and external characters, and its workflow mode was established on risk early-warning structure with integrated Entropy and D...

The delivery of user-tailored warning messages for heterogeneous user groups is a challenge rarely covered by hazard monitoring and Early Warning Systems (EWS) even though it is one of the four key elements of early warning systems identified by the United Nations International Strategy for Disaster Reduction (UN/ISDR). This article describes the concepts of generic information logistics develo...

Catastrophic and sudden collapses of ecosystems are sometimes preceded by early warning signals that potentially could be used to predict and prevent a forthcoming catastrophe. Universality of these early warning signals has been proposed, but no formal proof has been provided. Here, we show that in relatively simple ecological models the most commonly used early warning signals for a catastrop...

In the frame of the SISPyr project the feasibility of an Earthquake Early Warning system (EEW) covering Pyrenees is being studied. First of all, the analysis of the existing seismic stations shows that the SISPyr realtime network may be used as a base of a Pyrenean EEW despite that some difficulties exist to its implementation that should be solved. The exploration of an important Pyrenean wave...

This study takes our country's unified construction of rapid response system of food safety as the goal, regarding the model of early warning of food safety as the breakthrough point, combined with the analysis of the features of the early warning of the network, exploring the integrated ideas of the early forecast and early warning system of food safety information in China, so as to construct...
